ORACLE循环插入测试数据：
DECLARE v_num number(8):=2;v_index number(8):=1;v_name varchar2(255);v_code varchar2(15);
begin
while(v_index<=v_num)
loop
v_code:='000000000'||TO_CHAR(v_index);
v_name:='name_'||SUBSTR(v_code,length(v_code)-7);
insert into t_person(PERSON_NAME)
VALUES(v_name);
COMMIT;
v_index:=v_index+1;
END LOOP while_loop;
end;
